I get the following when attempting to play any sort of html5/h.264
video in chromium:

[75492:771764352:0116/062921:ERROR:context_group.cc(92)]
ContextGroup::Initialize failed because maximum renderbuffer size too
small.
[75492:771764352:0116/062921:ERROR:gles2_cmd_decoder.cc(2012)]
GpuScheduler::InitializeCommon failed because group failed to initialize.
[75490:771764352:0116/062921:ERROR:command_buffer_proxy_impl.cc(152)]
Failed to initialize command buffer service.
[75489:771764352:0116/062953:ERROR:ipc_channel_posix.cc(267)] connect
/tmp/CAE9763D61F3C6E915DAFFB25E2FAE2AA0110832.24.0.1312.52_service_ipc: No
such file or directory

What's failing is this type of call:

    glGetIntegerv(GL_MAX_RENDERBUFFER_SIZE, &val);

Which doesn't return an error, but also doesn't appear to return the
minimum value according to the spec as well.

I built a small test program to try getting a good value, but my
opengl fu is a bit lacking to debug this and I'm pretty sure I haven't
set up the correct context to make this call work.

Html5/h.264 vids used to work in earlier versions of chromium, but I
see that the code in this area has changed somewhat.

This is under -current/32bit-x86/NEW_XORG, any help/counter-examples
appreciated.
